As we know, the barrel forms the main part of a dart, which is key
factor of determining weight and quality of dart, nowadays,
tungsten-based heavy alloy billet is widely used as the standard
barrel material, for it has a specific gravity of 19.3(20℃), making
it a very dense material with small volume, besides, it has
superior wearing resistance, well machinability, and more

Today's standard material for barrel is tungsten heavy alloy, for
its special properties, nowadays tungsten is widely applied to make
darts replacing brass, because of technical difficulties with
manufacturing, a 100% tungsten dart is not available, all
"tungsten" darts you can buy are in fact made of tungsten heavy
alloys

We could supply tungsten heavy alloy billets by various sizes and
contents, popularly 70~90% tungsten is used for making both
soft-tip and steel tip barrels, ranging from 14~18 gram and 18~40
gram respectively, and sometimes, 65% and 95~97% tungsten are
offered following customers’ specific request

With strong funding, advanced manufacturing technology, strict
quality control, and a research and a research & development
team leaded by materials science professors and senior engineers,
our company gain support from relevant academy of Central South
University and foreign advanced technology. In addition, we own
more than 40 patents for invention and products appearance which
ensure our tungsten alloy products are in leading level in national
even in international.
